SPECIFICATION forming part of Letters Patent No. 713,976, dated November18, 1902.

Application lcd April 25, 1902.

To all whom, it may concern,.-

Bo it known that I, TRUMAN B. FUNK, of the city of Enid, Garfieldcounty, Territory of Oklahoma, have invented certain new and usefulImprovements in Grain-D rills,of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming a part hereof.

My invention relates to grain-drills; and it consists of the novelconstruction, combination, and arrangement of parts hereinafter shown,described, and claimed.

My object is to construct a grain-drill or seed-planter which willdeposit the seed in a deep and narrow furrow having an equal amount ofearth thrown up on each side of the furrow; and my invention consists ofthe combination in a grain-drill or the like with suitable frameworkhaving dropping tubes and means of conveying the seed into thedropping-tubes, of a disk-carrying frame havinga boot to receive thelower end of the dropping tube, said frame extendingT forwardly fromsaid boot at an angle first to one side and forming a bearing plate andthen turning to the other side and forming a second bearing-plate, atrunnion-base extending from the first bearing-plate, a trunnionbaseextending from the second bearingplate, trunnions extending from saidbases, and disks mounted upon said trunnions, the forward halves of saiddisks being in the same running line, and means of drawing said disks.

Figure 1 is a view, showing the axle in section, of a grain-drillembodyingthe principles of my invention. Fig. 2 is a top plan view,partly in section, of the disks shown in Fig. 1. Fig. 3 is adiagrammaticview showing how the disks dig the furrow, the sides of which are equal,with an equal amount of earth thrown up on each side of the furrow. Fig.4 is a sectional perspective of the hub of one of the disks.

Referring to the drawings in detail, the grain-dropping tube 5, thegrain-box 6, the axle 7, and their connecting parts, including thetraction-wheel 8, are of the usual construction; and my inventionconsists in detail of the combination,with the lower end of thegrain-dropping tube 5, of a disk-carrying frame comprising the boot 9 toreceive the Serial No. 104,718. (No model.)

seed from the dropping-tube, said frame extending forwardly from theboot at an angle first to one side and forming the bearingplate 10 andthen turning to the other side and forming the bearing-plate 11; thetongue 12, extending forwardly from the boot and providing means ofattachment to the draft apparatus; a trunnion-base 13, secured to thebearing-plate 10 by means of the bolt 14; the trunnion-base 15, secu redto the bearing-plate 1l by means of the bolt 16; the trunnion 17,extending from the trunuion-base 13; the trunnion 1S, extending fromthebase 15; the hub 19, mounted upon the trunnion 17; the hub 20, mountedupon the trunnion 18; the disk 21, mounted upon the hub 19, and the disk22, mounted upon the hub 20, the forward halves of said disks being inthe same running line so that the forward disk 22 will make the furrow23 and throw up the bank 24 by the outer side of the furrow and the reardisk 2l will make the furrow 25, said furrows 23 and 25 overlapping andthe bank 26 being thrown up from the furrow 25, said banks 24 and 26being substantially of the same size. The hubs 19 and 20 are formed asshown in detail in the sectional part of Fig. 2 and in Fig. 4. Thegroove 27 is formed in the inner face of the hub, thus producing theange 28,extending inwardly around the bore 29, said bore being adaptedto receive the bearing-surfaces of the trunnion 18 and the outer end ofsaid bore being reduced by the flange 30 to form the small opening 31 toreceive the screw-threaded neck of the trunnion. The connecting-rod 32connects the tongue 12 to the frame of the drill and provides a means ofdrawing the disk.

I am aware that disks have been used on grain-drills and the like formaking furrows to receive the seed; but I am not aware that the diskshave heretofore been mounted with the forward part of one disk in thesame running line as the forward part of the other disk7 so as to make afurrow the sides of which are equal and throw up an equal amount ofearth upon each side of the furrow.

I claim- The combination in a grain-drill or the like with suitableframework having droppingtubes, and means of conveying the seed into thedropping-tubes; of a disk-carrying frame IOO having a boot to receivethe lower' end of the dropping -tube, said frame extending for- Wardlyfrom said boot at an angle rst to one side and forming a bearing-plate,and then turning to the other side and forming a second bearing plate;a, trunnion base eX- tending from the first bearing-plate; atrunnionbase extending from the second bearing-plate; trunnionsextending from said lo bases and disks mounted upon said trunnions, theforward halves of said disks being in the same running line; and meansof drawing' said disks, substantially as specified.

In testimonywhereof I affix my signature in presence of two Witnesses.
